4.310 ent-gws-redirect

Use this command to provision the gateway screening redirect function. The Redirect table must be provisioned before configuring gateway screening to redirect received MSUs. The values that are specified with this command are stored in the Redirect table, and they are used to set the variable fields of the MSUs being redirected. For example, if the ri=gt parameter is specified, the value gt is set for the routing indicator in the called party address (CDPA) of the MSU being redirected.

Parameters

Note:

See Point Code Formats and Conversion for a detailed description of point code formats, rules for specification, and examples.
dpc (mandatory)
Specifies the value used to set the ANSI destination point code field in the routing label of the MSU that is being redirected. The ANSI point code has subfields network indicator-network cluster-network cluster member (ni-nc-ncm).
Synonym:
dpca
Range:
000-255

Specify a valid value for each subfield of the point code, and separate the subfields with a dash (-).

When chg-sid:pctype=ansi is specified, ni = 000 is not valid.

When chg-sid:pctype=ansi is specified, nc = 000 is not valid if ni = 001–005.

When chg-sid:pctype=ansi is specified, nc = 000 is valid if ni = 006–255.

The point code 000-000-000 is not a valid point code.

dpc/dpca/dpci/dpcn/dpcn24/dpcn16 (mandatory)
Destination point code.
dpci (mandatory)
Specifies the value used to set the ITU international destination point code field in the routing label of the MSU that is being redirected. The point code has subfields zone-area-id.
Range:
0-255

Specify a valid value for each subfield of the point code, and separate the subfields with a dash (-).

zone—0–7

area—000–255

id—0-7

The point code 0-000-0 is not a valid point code.

dpcn (mandatory)
Specifies the value used to set the ITU national destination point code field in the routing label of the MSU that is being redirected. The point code is in the format of a 5-digit number (nnnnn); or 2, 3, or 4 numbers (members) separated by dashes (m1-m2-m3-m4) when the chg-stpopts:npcfmti flexible point code option is on. A group code (gc) must be specified when the ITUDUPPC feature is on (nnnnn-gc, m1-m2-m3-m4-gc).
Range:
0-16383, aa-zz

Specify a valid value for each subfield of the point code, and separate the subfields with a dash (-).

nnnnn—0-16383

gc—aa-zz

m1-m2-m3-m4—0-14 for each member; values must sum to 14

dpcn24 (mandatory)
Specifies the value used to set the 24-bit ITU national destination point code field in the routing label of the MSU that is being redirected. The point code has subfields main signaling area-sub signaling area-signaling point (msa-ssa-sp).
Range:
000-255

Specify a valid value for each subfield of the point code, and separate the subfields with a dash (-).

msa—000–255

ssa—000–255

sp—000–255

dpcn16 (mandatory)
Specifies the value used to set the 16-bit ITU national destination point code field in the routing label of the MSU that is being redirected. The point code has subfields unit number-sub number area-main number area (un-sna-mna).
Range:
000---127
Specify a valid value for each subfield of the point code, and separate the subfields with a dash (-).
un---000---127
sna---000---15
mna---000---31
gta (mandatory)
Specifies the value used to set the global title address (dialed digits) in the SCCP called party address of the MSU being redirected.
Range:
1 - 21 digits
ri (mandatory)
Specifies the value used to set the routing indicator in the SCCP called party address of the MSU being redirected. Use the gt value to route by global title digits or use the ssn value to route by subsystem number.
Range:
gt
ssn
ssn (mandatory)
Specifies the value used to set the subsystem number (SSN) in the SCCP called party address of the MSU being redirected. This number is the SSN of the SCP to which all MSUs meeting the redirect criteria are to be redirected.
Range:000 - 255
tt (mandatory)
Identifies the type of the global title translation (GTT). This value is the decimal representation of the 1-byte field used in SS7 and is used to set the type of the GTT in the SCCP called party address of the MSU being redirected.
Range: 000 - 255
enabled (optional)
Specifies whether MSUs that have passed gateway screening are to be redirected (enabled=on) or routed as normal (enabled=off).
Range:
on
off
Default:
on

Example

ent-gws-redirect:dpc=1-40-1:ri=gt:ssn=10:tt=1:gta=180833:enabled=on

ent-gws-redirect:dpc=1-40-1:ri=ssn:ssn=10:tt=1:gta=1800833:enabled=off

ent-gws-redirect:dpcn16=1-14-0:ri=gt:ssn=10:tt=10:gta=1:enabled=on

Dependencies

The dpc/dpca/dpci/dpcn/dpcn24/dpcn16 parameter must be defined in the Destination table or defined as the STP site point code.

If the dpc/dpca/dpci/dpcn/dpcn24/dpcn16 parameter is defined as a destination, it must have at least one route defined.

The redirect function data can be entered only once.

Notes

The SCCP screening functions (CGPA, TT, CDPA, and AFTPC) cannot select an MSU to be redirected.

Do not apply a Redirect Stop Action on the Adjacent Node point code for the BLKOPC and OPC screening functions.

Do not apply a Redirect Stop Action for an allowed DPC screen rule if the rule contains the self-identity point code of the EAGLE where the screening rule is applied. This is because the redirection of SLTAs and SLTMs (Signal Link Test Messages and Acknowledgements) will not return to the originating EAGLE and will cause the link to fail.

If gwsa=off and gwsm=off are specified for all linksets, gateway screening and the GWS redirect function for the DTA feature are disabled.

Output

ent-gws-redirect:dpc=1-40-1:ri=gt:ssn=10:tt=1:gta=180833:enabled=on
